CHARLES A. SUI-IR, OF CHICAGO, ILLINOIS.

EARTH-AUGER.

Specification of Letters Patent.

Patent-ed Aug. 11, lgt.

Application led January 5, 1914. Serial No. 810,394.

To all whom it may concern Be it known that I, CHARLES A. SUHR, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Earth-Angers, of which the following is a specification. l

My invention relates to impro-vements in earth augers and has for its object the provision of an improved construction of this character the blades of which may be readily sharpened or reset andwhich is strong and durable in use. i

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understoodby reference to the accompanying drawing forming a part of this specification, and in which* Figure l is a partial side view, shown partially in section, of an earth auger embodying my invention, Fig. 2, a section taken on line xof Fig. l, and Fig. 3, a section taken on line y-y of Fig. 2.

The preferred form of construction as illustrated in the drawing comprises the usual auger blades l which are adapted to bore a hole, such as a post hole in the earth when turned, as will be readilyunderstood by those skilled in the art. At its upper end each of the blades l is provided with a bracket 2 which extends but little above the upper end of the blade and then turns inwardly sharply at substantially right angles to said blades and overlaps the corresponding portion of the bracket on the other blade. Each of the brackets 2 is recessed at 3 to receive the corresponding portion of the. other bracket so that when said brackets are secured together, they form practically a continuous yoke or bridge connecting the blades. Each of the brackets is provided with one half of a handle socket 4 pro-vided at the bottom with a flange 5, said handle socket portions and flange being so shaped as to complete a socket having a closed bottom when said bracket members 2 are secured together by means of bolts 6 as indicated. After the socket has been completed by securing the bracket members together by bolts 6, said Vsocket is threaded and a handle 7 is threaded to fit into said socket as shown. At its upper end the handle 7 is provided with a cross bar 8 to facilitate the turning of the `blades in the earth for forming a hole therein as will be readily understood. By this ai rangement it will be observed that the biades l may be readily detached from each other and the handle to facilitate sharpening or resetting of the same. By extending the brackets 2 upwardly from blades l but little and turning them inwardly and sharply at substantially right angles thereto, the connection Awith the handle 7 is made at the shortest possible distance from the blades thus subjecting the socket portions and the connecting bolt 6 to the minimum strain when the implement is in actual use. Inasmuch as the auger action of the blades introduces large strains into the implement which, of course, are increased immensely when a stone or other hard object is encountered, the strength of the handle connection and the character of the strain transmitted thereto is of much importance, and this arrangement of the brackets is well adapted to resist such strains. By providing a handle socket with a closed bottom the strength of the arrangement is further increased.

While I have illustrated and described the preferred form of construction for carrying my invention into efl'ect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifica-tions as come within the scope of the appended claims.

Having described my invention what I claim is new and desire Patent is:

1. An earth auger comprising two blades; a supporting bracket at the upper end of each of said blades; each of .said brackets being provided with a portion of a handle socket cooperating with the portion on the other to complete the socket when said brackets are secured together; means for de *tachably securing said brackets together;

and a handle secured in said socket, substantially as described.

2. An earth auger comprising two blades; a supporting bracket at the upper end of each of said blades, each of said brackets be ing provided with a portion of a threaded handle socket coperating with a portion on to secure by Letters the other to complete the socket when said ybrackets are secured together; means for detachably securing said bracketstogether; and a handle threaded in said socket, substantially as described.

l 3. An earth auger comprising two blades; a supporting bracketjat the upper lend of` each of said blades, each of said brackets being provided with a portion of a handle ,socket coperating With the portion on the other to complete a socket ihaving a closed bottom when said brackets are secured `to- Y gether; means for detachably securing said cur-ing said brackets together; `and Ia handle threaded inv said v'socket-v,fsubstantially as described.

\ -en'd 'of `each of said blades, said brackets eX- -tending but slightly above said blades and then turning inwardly sharply at substantially rightanglesto the blades and overlapping eachy other, each of said brackets being provided with a portion of a threaded handle socket cojpera'ting with the portionl on thje oth'er to complete a socket having a closed bottom when said brackets are secured together; means for detachably se curing 'said brackets together; and a handle threaded in SaidsOcket, substantially as described.

1n testimony whereof I have signed my name to "this specification in 'the presence of two isubscrlb'ln'g witnesses.
